de.grogra.imp2d.layout.HierarchyLayout

All Implemented Interfaces:

Manageable, Shareable

public abstract class HierarchyLayout
extends Layout

A HierarchyLayout computes a graph layout based on a hierarchy model. The concrete hierarchy model has to be implemented in subclasses (e. g. TreeLayout, SugiyamaLayout)
